ABSTRACT

A car starter battery includes a housing accommodating therein multiple sets of lithium cells, a carrying-handle located on the top side of the top cover of the housing, two conducting screw holes located on the top cover at two opposite sides relative to the carrying-handle and electrically connected with the lithium polymer cells for the connection of a jumper cable with conducting screw terminals, and a charging-discharging copper screw detachably threaded into each of the two conducting screw holes for the connection of a jumper cable with conducting terminal clamps.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to starter batteries for car and moreparticularly, to a car starter battery, which has the characteristics ofhigh capacity, light weight, long lifespan, environment protection andreduction of the load of the car starter, and allows connection todifferent cars by means of different jumper cables.

2. Description of the Related Art

Lead-acid batteries are commonly used as starter batteries for car.However, a lead-acid battery has low charging/discharging performanceand not allow for reversing output polarity. Further, conventional carstarter batteries are not highly stable, and may be suddenlyover-consumed, causing the driver unable to start the car and leading totravel delay or traffic impact. Further, conventional car starterbatteries simply provides a power examination function without automaticpower-off and balance charging and discharging control functions. Thus,the problems of battery power attenuation and loss are commonly seen inconventional car starter batteries.

Further, conventional car starter batteries are designed for use inspecific models of cars. Different models of cars cannot use one sametype of car starter battery. Further, conventional car starter batteriesare not applicable in different geographical areas that exhibitsignificant temperature differences.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances inview. It is the main object of the present invention to provide a carstarter battery, which allows connection to different cars by means ofdifferent jumper cables, provides a polarity-reversed output control tofit different cars and a standby power supply for emergency starting.

It is another object of the present invention to provide a car starterbattery, which has the characteristics of thermostat control, electricalpower and voltage measurement and automatic power-off control, assuringa high level power-supplying stability.

To achieve these and other objects of the present invention, a carstarter battery comprises a housing accommodating therein multiple setsof lithium cells, a control circuit assembly for polarity-reversedoutput control, thermostat control, electrical power and voltagemeasurement and automatic power-off control, carrying-handle located onthe top side of the top cover of the housing, two conducting screw holeslocated on the top cover at two opposite sides relative to thecarrying-handle and electrically connected with the lithium polymercells for the connection of a jumper cable with conducting screwterminals, and a charging-discharging copper screw detachably threadedinto each of the two conducting screw holes for the connection of ajumper cable with conducting terminal clamps.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 2, a car starter battery in accordance with thepresent invention is shown. As illustrated, the car starter batterycomprises a housing 10, and multiple sets of lithium polymer cells (notshown) set in the housing 10. The car starter battery has thecharacteristics of high capacity, light weight, long lifespan,environment protection and reduction of the load of the car starter.

The power supply of the multiple sets of lithium polymer cells ismajorly adapted for starting the car under a normal condition, andpartially used as standby power supply for emergency starting. The carstarter battery has built therein a control circuit assembly forpolarity-reversed output control, thermostat control, electrical powerand voltage measurement and automatic power-off control. As this controlcircuit assembly is of the known art and not within the spirit and scopeof the present invention, no further detailed description in this regardis necessary.

The car starter battery further comprises a carrying-handle 20 locatedon the top side of the top cover of the housing 10, and two conductingscrew holes 40 located on the top cover of the housing 10 at twoopposite sides relative to the carrying-handle 20 and electricallyconnected with the multiple sets of lithium polymer cells in the housing10 for power input/output.

Further, a charging-discharging copper screw 30 is detachably threadedinto each of the conducting screw holes 40 for the connection of any ofa variety of jumper cables for different cars (see FIGS. 3 and 4).

The car starter battery further comprises an examination port 50, apower switch 60 and an indicator light 70 located on the back side ofthe top cover of the housing 10 (see FIG. 2). The examination port 50 isadapted for the connection of a computer for electrical power andvoltage measurement and cell failure examination, facilitating repairand replacement of any individual lithium cell. The power switch 60 isadapted for switching on/off standby power supply for starting the carunder an emergency condition. The indicator light 70 is adapted forindicating the on/off status of the standby power supply (the powerswitch 60). Further, a cable may be used to electrically connect theexamination port 50 to an analog power meter (not shown) that can bemounted at the dashboard of the car so that the car driver can visuallycheck the power and voltage indications of the analog power meter whendriving the car.

FIG. 5 illustrates an application example of the present invention. Asillustrated, after removal of the charging-discharging copper screwsfrom the conducting screw holes 40 of the car starter battery, twoconducting screw terminals 80 of a jumper cable are respectivelyconnected to the conducting screw holes 40 of the car starter batteryfor power transmission.

FIG. 6 illustrates another application example of the present invention.As illustrated, two conducting terminal clamps 90 of a jumper cable arerespectively fastened to the charging-discharging copper screws 30 inthe conducting screw holes 40 of the car starter battery for powertransmission.

Although a particular embodiment of the invention has been described indetail for purposes of illustration, various modifications andenhancements may be made without departing from the spirit and scope ofthe invention. Accordingly, the invention is not to be limited except asby the appended claims.
